Patent DE-2619442-A1 (DE)
Title: Electric printing mechanism with needle electrodes - has printing comb with insulated electrodes pressed by spring system against print carrier
Inventor: WIEDEMANN WALDEMAR
IPC: B41J2/425
Filed: 1976-05-03
Abstract: Electric printing unit has a printing comb with needle printing electrodes (2) which are arranged in a row and electrically insulated from one another. The tips of the electrodes rest on the surface of the printing carrier (3) which is guided over a roller (4). The printing pressure over the electrodes is equalised by a sprint arrangement (6) having for example a V-shape whose top rests on the inside of the housing and whose ends are supported on the sides of the printing comb. The spring is a plate spring and ensures that the pressure exerted on shorter, worn electrodes on one side of the comb is the same as that exerted on longer, less worn electrodes on the other side.

Title: Repair of underground steel tank - using laminated plastic and expanded foam insulator
IPC: B65D90/04
Filed: 1976-05-11
Abstract: Large steel tanks which are defective due to corrosion, are mended by building up the tank walls from the inside, in cases where they are located under-ground. Since the application of laminated plastic has to be carried out under controlled temperature, heat insulation on the tank wall provides the required condition. Expanded PVC-foam sheets (3) of 2-15 mm thickness are bonded to the inside of the tank wall (1). The laminated plastic (4) is then bonded to the insulation. Beside being a heat insulator, the foam (3) also provides a damping layer against vibrations.

Abstract: Prodn. of sound-absorbing floor covering materials involves applying a mixt. (I) of plasticised PVC and blowing agent to the back of a compact plasticised PVC sheet, opt. having a decorative coating on the front, and heating to convert (I) to a porous plastics material, pref. with simultaneous gelation. A plasticised PVC dispersion (II) of medium viscosity is applied to a temporary support and gell by heating, pref. to 110-160 degrees C, then coated with (I) based on (II) and heated to pref. 160-190 degrees C to effect foaming and gelation. The front of the material can have a transparent plasticised PVC film with a decorative print. The compact sheet is 0.1-2 mm thick, whilst the total thickness of the material is 1-6 mm. The material is highly sound absorbing, esp. for footfalls, and has good wear and load-bearing properties. It can be made easily and cheaply.

Title: Stabilising dehydrogenases, esp. alcohol dehydrogenase - by contact with aq. soln. contg. phosphate buffer, albumin, glycine and cysteine
Inventor: FRESENIUS REMIGIUS
IPC: A61K38/44
Filed: 1976-07-02
Abstract: Stabilisation of dehydrogenases is improved by adding cystein, in addn. to phosphate buffer, albumin and glycine, to the treatment soln. coming into contact with the dehydrogenase. Dehydrogenases are used in biochemical esp. quantitative-analytical processes. Thus, EtOH in blood or urine can be estimated quantitatively by adding alcohol-dehydrogenase, as catalysing enzyme, and nicotinamide-adenine-dinucleotide as coenzyme. Cystein addn. improves stabilisation to an extent such that aq. solns. of the dehydrogenases can be stored for longer periods or that the dehydrogenases can be used in carrier-bonded condition.

Title: Multi-colour screen printing machine with single drying station - moves sheet to drying station after each colour printing
Inventor: BECHER MANFRED
IPC: B41F15/08
Filed: 1977-04-27

Title: Stereoscopic camera for roll film - operates with film strip at angle and separate frames spaced laterally and vertically
Inventor: WINSTON RONALD H
IPC: G03B35/10
Filed: 1977-06-30
Abstract: The stereoscopic camera has the film strip running inclined to the horizontal, from a higher to the lower reel. The angle of the film and the spacing of the separate optics is such that the two corresponding frames (L16, R16, L17, R17) are focussed at the same height in the camera, but with one frame on the top half of the film strip and the other on the bottom half. The two frames are thus spaced laterally as well as vertically on the film. Successive frame pairs are exposed with any length of film strip, even with simple cine film. The projector/viewer has a similar arrangement so that the corresponding pairs of frames are accurately positioned for viewing. A simple and economic stereo system is provided, using conventional film.
